Which portion of the phosphatidylinositol molecule contributes to (a) fluidity of the bilayer and (b) the surface polarity of the bilayer?
Match the definitions with the words:
Direct Diffusion, Facilitated Transport, Active Transport
a) passive movement of molecules through a protein channel, down the solute's concentration gradient
b) using a vesicle to move many molecules into a cell
c) movement of molecules through a protein transporter, requires ATP, against the solute's concentration gradient
While endocytosis and exocytosis refer to the direction in which a vesicle moves into and out of a cell respectively, it is
important to think about what is being moved with and within the vesicles. To demonstrate how this process is utilized
in human cells we will focus on the human body's insulin response. The purpose of the insulin response is to create a
pathway for glucose entry into cells by releasing glucose transporters into the membrane.
Cell Type #1- insulin producers: In humans, pancreatic B-cells create steroid insulin that can be packaged into vesicles
starting at the ER. These vesicles are prepared for exocytosis so that the insulin can be released from the pancreatic B -
cells and get into the bloodstream when signaled to do so. When glucose is present in the blood stream these cells will
release the pre-packed insulin into the blood stream.
Cell Type #2- insulin responders: Other cells do not produce insulin but instead respond when they have received the
insulin signal…
